I'm on a z/OS only system with no specialty engines. From looking at the current Principles of Operation, and based on the fact that the D M=CPU on z/OS and the Q PROC on z/VM can display this information, I would say that it is very likely that the STSI privileged instruction returns this information. On page 10-148, it shows a construct called the TLE which is a part of the SYSIB 15.1.2 (Configuration Topology) which is labelled "CPU Type" and is described: <quote> CPU Type: Byte 1 of word 1 of a CPU-type TLE specifies an 8-bit unsigned binary integer whose value is the CPU type of the one or more CPUs rep- resented by the TLE. The CPU-type value specifies either a primary-CPU type or any one of the possible secondary-CPU types. </quote>
I _believe_ that "primary-CPU type" means "general CP" and "secondary-CPU types" refer to "specialty engines" such as IFL, zIIP, and zAAP. But I cannot find any confirmation of this. Or any indication as to what the value of each type of CPU might be.
